Clint Morgan commented on HBASE-584:
------------------------------------

Yes, I see the reasoning for the API policy, etc. 

Please reread my previous comment. 

>From a practical point of view, I don't understand how you plan to add new 
>methods to an interface and still think that a users RowFilter's 
>implementation would work. Adding new methods to the interface, will cause a 
>compile failure regardless of deprecated tags. (Unless we can provide default 
>implementations (eg that delegate to old methods) in an abstract class. But 
>there is no such Abstract class).

What am I missing?



> Names in the filter interface are confusing

> I don't like the names of the filter methods in RowFilterInterface. They 
> don't really tell how the methods are being used in the implementation of 
> scanners.
> I'd like to change:
>  - filter(Text) to filterRow(...)
>  - filter(Text, Text, byte[]) to filterColumn(...)
>   and the worst one is
>  - filterNotNull(SortedMap<Text, byte[]>). This should be filterRow(Text, 
> SortedMap<Text, byte[]>) (so we add the row key/).
> It may be nice to have timestamps in the methods as well? 
> Also the java doc could be cleaned and improved to tell how the filtering is 
> implemented (check rows keys first, then check each individual columns, 
> finally check the assembled row)
> Upon positive feedback, and I'll create a patch.
